Climax Metal Products M1C-30 Clamp Shaft Collar

Product Description

The CLIMAX METAL PRODUCTS M1C-30 is a one-piece clamp-style shaft collar machined from steel with a black oxide finish. It features a plain bore and is designed to secure rotating shafts, position components, and serve as mechanical stops or spacers in drive assemblies, conveyor systems, and industrial machinery. The outside diameter measures 2.125 inches and the bore diameter is approximately 1.181 inches. The clamp design allows for tool-based tightening without marring the shaft surface, making it a reliable choice for maintenance and OEM applications alike. Installation is handled by mechanical and millwright trades.

This shaft collar is suited for light to medium-duty industrial and mechanical applications where positive shaft retention is required. Typical use cases include electric motor shafts, pump shafts, gearbox assemblies, and similar rotating equipment. The black oxide finish provides a degree of corrosion resistance in dry or mildly humid environments. The M1C series from CLIMAX METAL PRODUCTS is produced under ISO 9001:2008 quality standards, making it appropriate for applications where dimensional consistency and material traceability are required.

Installation Notes

Shaft collars of this type are installed by millwrights, mechanical technicians, or maintenance professionals using standard hex keys or socket wrenches. Before installation, de-energize and lock out the equipment per applicable OSHA lockout/tagout procedures. Ensure the shaft surface is clean and free of burrs before positioning the collar. Do not use the collar as a primary bearing load component unless the assembly is specifically rated for that purpose.
